So the new champion is some sort of war pet animal from Noxus?

"KLED" is the signer of the posters, I don't think the champion is named after that.

Anyone thought Kled might be an acronym for a Rioter? The one behind its design? I don't know many Red names so...

Anyways, on to the champion itself

The 3 posters have 3 different views on him, one talks about him, "he runs in a straight line and stinks like Sion", the other says he's a coward, and the last one mentions him being the "pride of noxus" and that "patrolling isn't the same without him".

All signed by the same person, why would "Kled" have different opinions on this animal?

Is he some sort of Noxian mount I wonder? Can a champion hop on him? He seems like the creature military personel would use to cover large areas. Split-pusher? map control? diver?

In the last poster it seems like there's arrows flying his ways and/or breaking on impact with his chest. It really feels OH EPIFANY WHILE RIGHTING xp

Why the teaser in the bush ALSO? MAYBE this champion is a "face-checker" of bushes, like when you're down to inibitor towers and you have 0 vision, and you want to facecheck bushes and patrol the jungle.

A support maybe? The ADC can mount him, and together they can facecheck the fog of war!
